Patent CA-2131737-A1 (CA)
Inventor: LAMPANI RICHARD A
IPC: F16H59/04
Filed: 1994-09-09
Abstract: A drop-in shifter for an automotive transmission is provided. The drop-in shifter includes a shift stick, a base including a socket, a semispherically-shaped pivot operably connected to the shift stick for pivotally mounting the shift stick to the socket on the base, and a spring positioned over a laterally extending rocker pin that extends from the shift stick for engaging the ends of the rocker pin to bias the shift stick to a centered neutral position. A cover is configured to mateably engage the base and retain the assembly together, the cover including protrusions configured to slidingly engage the base and then rotate under locking surfaces to securely retain the cover to the base. The cover holds the spring in a compressed position on the base and further retains the pivotable shift stick on the base without the need for separate fasteners. The cover can be assembled to the base without the need for separate fasteners, and includes a locking pin configured to interlockingly engage the base and prevent rotation and accidental disassembly once securely engaged therewith.
Patent CA-2132235-A1 (CA)
Inventor: SCHULTZ WAYNE L
IPC: B61B11/00
Filed: 1994-09-16
Abstract: A ski  tow arrangement  having  a  single  endless conveyor belt running on and directly supported by the snow, without the typical conveyor framing and idler rollers along the length of the belt.  Both the loaded and return belt run flat  on  the  snow,  side  by  side  with  adequate  lateral spacing, instead of the usual conveyor arrangement of loaded belt above the return belt.   At each terminal  four belt rollers, two horizontal and two vertical, serve to reverse the belt direction and provide adequate lateral  spacing.          Power is applied by conventional means to the head pulley of the uphill terminal.  The upper belt surface may be provided with cleats to hold the skier in position during slippery belt  conditions  on  steeper  slopes.     To   facilitate comfortable loading without a significant change in skier momentum,  a snow ramp allows the skier to accelerate to match the belt speed prior to arriving on the belt at the lower terminal.   Similarly the snow slopes away from the discharge end of the belt at the upper terminal to allow skiers to exit away from the ski belt and on down the hill by the force of gravity.

Title: Process and device for removing heavy metals and compounds containing heavy metals
Inventor: ULRICH KLAUS H
IPC: C21C5/38
Filed: 1994-12-06
Abstract: A process and device for removing heavy metals and compounds containing heavy metals from waste gas of a metallurgical vessel which is charged with materials posing disposal problems. The flue gas collecting in the metallurgicalvessel is sucked out of the vessel as a main gas flow and cleaned in a gas cleaning system. The flow of cleaned gas is guided to an after-burning device. A portion of the clean flue gas is diverted from the main gas flow leading to the after-burning device. The diverted flow portion is cooled and guided back to the main flow of flue gas where it is meixed with the flue gas before the main flow of flue gas enters the gas cleaning system.

Title: Lottery ticket paper
Inventor: WATSON MARK V
IPC: B42D15/10
Filed: 1995-02-07
Abstract: A lottery ticket, for example of the "instant" scratch-off kind, comprises a non-opaque base paper and a coating layer or layers positioned between the base paper and win-or-lose indicia carried by the ticket.  The coating is not self-supporting,  so  that  it  is  not  itself  susceptible  to fraudulent delamination,  and is opaque with respect to transmitted  light.    Thus  even  if  the  base  paper  is delaminated,  the  win-or-lose  indicia  are  still  not discernible on viewing the ticket against a high intensity light source, since the opaque coating is still between the indicia and the light source.  The desired opacity of the coating is achieved by the use of opaque pigments such as carbon black or aluminium powder or flake.   The opaque coating can carry a light-coloured topcoat for enhanced printability, or a lustrous topcoat giving an attractive decorative effect.

Title: System for separating solids from a liquid
Inventor: LEE CHARLES A
IPC: B01D33/46
Filed: 1993-08-27
Abstract: System (10) for separating solids from slurry (12) from a source (14). The slurry (12) is flowed into a separation channel (20) positioned over a moving foraminous medium (26) to effect cross flow separation of liquid from the slurry (12) in an initial channel section (21) followed by separation of solids from the slurry (12) in a second channel section (23), all the separation being effected employing the moving foraminous medium (26). The flow rate of slurry (12), the rate of travel of the foraminous medium (26), and the differential pressure across the foraminous medium (26), as established by the pressure exerted by the flowing slurry on the foraminous medium (26) and the relative pressure underneath the foraminous medium (26), are controlled in different compartments (34a-34d) underneath the length of the separation channel (20) to provide optimum steady state separation.

Inventor: STROCK THOMAS W
IPC: F23G5/00
Filed: 1995-05-01
Abstract: A device for deflecting a liquid slurry flow in a housing away from an inlet flue conveying hot flue gas to the housing, the device having an upper surface and communicating with the housing at an inner wall of the housing. An inlet awning having a bottom portion horizontally extends into the housing from an upper surface of the inlet flue. An inclined top portion is connected to the bottom portion and an inner wall of the housing, the top portion extending upwardly at an incline from the bottom portion to the inner wall of the housing, the top portion having sufficient area to collect liquid slurry in excess of that required to achieve instant cooling and humidification of the hot flue gas, the top and bottom portions forming a tip at an area where the top portion is connected to the bottom portion. An extension outwardly extends from the tip of the inlet awning and slightly below the bottom portion of the inlet awning in order to deflect the liquid slurry flow away from the bottom portion of the inlet awning to keep the bottom portion dry and thereby prevent build-up of slurry deposits at the inlet flue.

Patent CA-2149112-A1 (CA)
Title: Low-noise operation of a machine fed by a pulse inverter
Inventor: STEMMLER HERBERT
IPC: H02P27/08
Filed: 1995-05-09
Abstract: With this method for the low-noise operation of a machine driven by a pulse inverter, the amplitudes and frequencies of the harmonics of the inverter output voltages let themselves be computed.  Through targeted setting of the modulation parameters, the frequency spectrum or the noise spectrum can be fanned out and harmonics, which would excite stator resonances, can be eliminated.  Due to the independence of the modulation parameters of the modulation index (a0) and the fundamental oscillation frequency (f1), the fanning-out and the elimination has no influence on the fundamental oscillation (uGS) or the operating point of the machine. The control of the inverter takes place through sinusoidal pulse width modulation (PWM) and sinusoidal modulation (PFM) of the triangular carrier signal (uH).  By this method, the main groups of the harmonics with two ordinate numbers (n, v) are fanned out into subgroups with three ordinate numbers (n, m, v).  Apart from a more uniform distribution, also a reduction in the amplitudes of the harmonics (Unmv) arises through this fanning-out.  The noise arising in that case on the one hand displays a reduced level and, on the other hand, the sound pattern no longer has any conspicuous individual frequencies and is perceived as noise.

Title: Negative birefringent polyimide films
Inventor: HARRIS FRANK W
IPC: C08G73/16
Filed: 1994-04-21
Abstract: A negative birefringent film, useful in liquid crystal displays (2), and a method for controlling the negative birefringence of a polyimide film is disclosed which allows the matching of an application to a targeted amount of birefringence by controlling the degree of in-plane orientation of the polyimide by the selection of functional groups within both the diamine and dianhydride segments of the polyimide which affect the polyimide backbone chain rigidity, linearity, and symmetry. The higher the rigidity, linearity and symmetry of the polyimide backbone, the larger the value of the negative birefringence of the polyimide film.
